The second version of Luoshiqi Technology's LQ3568 core board uses a single-chip LPDDR4 design. The measured main frequency has reached 1.5GHz, which is double the design of the first-generation two-chip DDR3. The performance is improved and the cost is also reduced. The LQ3568 core board supports dual Gigabit Ethernet, USB3.0, SATA, WIFI6, and can be widely used in the Internet of Things, cloud terminals, industrial control, vehicle central control, edge computing and other fields, so stay tuned.

Description of LQ3568 core board independently developed by Luoshiqi Technology:


1. It integrates GPU, VPU, and NPU co-processing, and has strong video coding and decoding capabilities, which can be switched in one-click among DC architecture models such as Caffe/TesorFlow;


  2. Luoshiqi 3568 core board adopts dual-channel LPDDR4 design, the main frequency is up to 1.5GHz, with low cost and high cost performance;


  3. The number of pins is as high as 200pin, which brings out almost all the functional characteristics of the CPU, which is convenient for customers to develop;


  4. The size is only 55.8mm*55.8mm, with large expandable space;


  5. Support dual Gigabit Ethernet, WiFi6, USB3.0, SATA, etc., with complete functions;


  6. The core board has undergone a large number of drop tests, high and low temperature tests, aging tests, stable performance, and the baking machine runs normally for 7 days * 24 hours.
